IIRC, you would want your torque converter to stall slightly below peak torque. For drag racing.
Just because you get a torque converter that has a stall speed of say 3200 RPM, does not mean your truck will not really move until 3200 RPM's is reached. (for the newbies)
When you get a good quality torque converter, they do not slip that much & will drive just like a low stall converter, that is until you get on the throttle hard, then that 3200 stall converter will reach that RPM quickly.
If you are not too worried about taking off the absolute best it can, and would be able to light up the tires if needed to. then I would say a 2600-2800 stall.
Make sure it is a lock-up converter, so your mileage is not too bad when using a higher stall converter.
It depends on what you want out of your vehicle. Race it, street vehicle, do you want best mileage possible & not worried about getting the best take off?
